Misdiagnosis of Wheezing

Misdiagnosis and Wheezing

Sinusitis is overdiagnosed: There is a tendency to give a diagnosis of sinusitis, when the condition is really a harmless complication of another infection, such as a common cold.

Whooping cough often undiagnosed: Although most children in the Western world have been immunized against whooping cough (also called "pertussis"), this protection wears off after about 15 years. Thus, any teen or adult with a persistent cough may actually have whooping cough. This is particularly dangerous for babies too young to be vaccinated, and any un-vaccinated children. Whooping cough can be fatal to an infant. The cough symptoms of whooping cough is usually productive initially, but then becomes a persistent dry cough, lasting up to 100 days. Elderly grandparents may also be a reservoir of undiagnosed whooping cough.

Chronic lung diseases hard to diagnose: Some of the chronic lung diseases are difficult to diagnose. Even the well-knowns conditions such as asthma or lung cancer often fail to be diagnosed early. Some of the chronic lung diseases with diagnostic difficulties include asthma (perhaps surprisingly), COPD, emphysema, chronic bronchitis, cystic fibrosis, mesothelioma, smoker's cough, AIDS-related respiratory conditions (see AIDS), chronic pneumonia, and other respiratory diseases. Rare possibilities include diseases like psittacosis (bird-related lung infection). See other types of chronic lung diseases.

Severe asthma is a medical emergency: Severe asthma is a life threatening condition that is resistant to standard treatment and requires intensive medication to overcome the obstruction to the air passages. Studies suggest that asthma is often underdiagnosed. In elderly patients, diseases such as bronchitis or emphysema are relatively common. Proper diagnosis in these patients can be further complicated by the difficulty some older people have performing pulmonary function tests. However, it is important to determine the extent of reversibility of the airflow obstruction. In children younger than age 5, the most common cause of asthmatic symptoms is a viral upper respiratory tract infection.

Poor prognosis for small cell cancer of lung: Small cell cancer of the lung is the leading cause of death. It is an undifferentiated tumour, which usually involves the right upper lobe of the lung parenchyma. It can easily spread through blood to distant organs. At the time of diagnosis the tumour is well spread to other tissues, as the tumour is highly invasive. The tumour is associated with the production of hormones adrenocorticotropins or ACTH. Smoking is the risk factor for the formation of the tumour. The tumour is sensitive to chemotherapy and radiation therapy. Surgery is usually not a treatment option even when the tumour is small. With treatment the survival can be upto one year.
